“We’ve seen it with Trump Vodka, we’ve seen it with Trump mortgage, we’ve seen it with all of his Trump endeavors. And right now, he’s being sued for fraud with Trump University. Every single one of them has failed,” Haley said.

Republican Nebraska Sen. Ben Sasse said that he could neither support nor vote for the billionaire businessman — and that a third candidate would be a better choice than Trump or Democrat Hillary Clinton.

Trump’s two main opponents continued hammering him on the campaign trail.

“I’ll go anywhere and speak to anyone before I let a con artist get a hold of the party,” Rubio said about Trump.

“If we nominate Donald Trump, in all likelihood Hillary Clinton will win,” Ted Cruz said. “We don’t want the general election to be between two rich New York liberals.”

Cruz and Rubio also called on Trump and The New York Times to release a recording of an off-the-record talk The Donald had with the paper’s editorial board in January, charging that he told the board he didn’t really plan to impose harsh, anti-immigration measures if elected.

“The voters deserve to know if he says something different when he’s talking to The New York Times than he does when he’s talking to the voters,” Cruz said. “And we deserve to know before Super Tuesday.”
